基于IEC 61850的保护功能交互模型

Interaction Model of Protection Functions Based on IEC 61850

为了更好地实现基于IEC61850的分布式功能的标准化设计、促进系统的工程实施,需要对保护功能在智能电子设备(IED)之间、IED内部逻辑节点(LN)之间的交互关系进行严谨的描述。文中为IED的交互过程构建了一个较统一的功能模型,阐述IED之间、IED内部LN之间的交互类型,采用扩展协作图和时序图分别刻画分布式保护功能下各LN之间的协作和时序关系,设计了IED的软件结构,为互操作测试实验提供了一定的参考。

In order to fulfill the standardization design and engineering application for distributed protection functions based on IEC 61850, the interaction relations among intelligent electrical devices （IEDs） and different logical nodes （LNs） under the protection functions need to be described strictly. A unified function model is proposed for the interaction process of IED and the interaction modes among IEDs and LNs are expatiated. The extended collaborative and sequence diagrams are studied to embody the cooperative association and time sequence among LNs under the distributed protections. At last, the software architecture of IED is designed. The interaction model may give a reference for the interoperating tests.
